I've been learning Stay With me. I've seen at least six different bass tab and a video, all different. The Faces played it live differently from the record and there seem to be two different studio versions with long and short endings. These all have inconsistent bass lines, especially at the end. Aside from getting the introdsuction spot on, I think hat for most of teh song its the distinctive rhythm that matters.
There' also Feel Like Making Love, where there a very distinctive riff with a pronounced slur, this is followed by a little pentatonic run. The first bit needs to be spot on to get the feel of the song, the second bit it seems to be largely improvised and is much quieter anyway.
So my thought is to decide which bits define the feel of the song or set up changes, and get those right.
